The bolt on my Victor stopped staying cocked back and would just got into "autofire" mode if I put a tank on the gun.
Took the trigger frame off and noticed that a spring is broken in the trigger frame.

The rocking piece that sticks up out of the trigger frame and catches the striker between shots has a spring attached to it that keeps tension on it so it catches the stricker. That spring broke. I haven't been able to find a replacement, and ideas?
